Kate Middleton seen with Prince William before he joined Queen Camilla at Commonwealth Day event

The Prince and Princess of Wales were spotted heading out of Windsor Castle near London on Monday amid a tense time for the royal family.

Prince William and Kate Middleton sat in the backseat of a chauffeured vehicle just hours after the princess apologized for editing a family photo.

On Sunday, the Princess of Wales shared a photo with her three children – Prince George, Prince Louis and Princess Charlotte – to celebrate Mother’s Day in the United Kingdom on the royal social media accounts.

Middleton apologized one day later, after admitting that the image shared online had been edited.

Queen Camilla and Prince William led the royal procession as the congregation sang “God Save the King.” King Charles, who was diagnosed with cancer last month, was not in attendance.

His Majesty appeared in a pre-recorded video message to pay tribute to the Commonwealth, which is composed of 56 independent and equal countries previously under the British Empire.

“As I have said before, the Commonwealth is like the wiring of a house, and its people, our energy and our ideas are the current that runs through those wires,” King Charles said in his speech.

He briefly addressed his cancer diagnosis, saying, “In recent weeks, I have been most deeply touched by your wonderfully kind and thoughtful good wishes for my health and, in return, can only continue to serve you, to the best of my ability, throughout the Commonwealth. My belief in our shared endeavours and in the potential of our people remains as sure and strong as it has ever been. I have no doubt that we will continue to support one another across the Commonwealth as, together, we continue this vital journey.”

The annual royal tradition was somewhat overshadowed by Kate Middleton’s photo sharing scandal on Mother’s Day.

After the photo was released, eagle-eyed followers soon noticed the image appeared to be distorted. The Associated Press and other news agencies began pulling the image from their websites over concerns that it was “manipulated.”

Middleton took to social media to issue a statement, writing, “Like many amateur photographers, I do occasionally experiment with editing. I wanted to express my apologies for any confusion the family photograph we shared yesterday caused.”

“I hope everyone celebrating had a very happy Mother’s Day.”

Middleton has remained out of the public eye since Dec. 25. She was admitted into the hospital for a planned abdominal surgery on Jan. 17, and has only been spotted once since her hospitalization.

Earlier this month, a spokesperson for Kensington Palace, which handles the household for the Prince and Princess of Wales, told Fox News Digital: “Kensington Palace made it clear in January the timelines of the Princess’ recovery and we’d only be providing significant updates. The guidance in January stands that the Princess would be recuperating at home in Windsor.”

The spokesperson reiterated the princess is “doing well.”

The statement came amid a flurry of conspiracy theories that emerged on sites like X, formerly known as Twitter, and TikTok, with users speculating about the royal’s whereabouts and health condition. The hashtag #WhereisKate previously went viral on the social media platforms.
